You need to catch a bus from metro Manila to Batangas. You have awide array of buses to choose from, suggest a "delux" bus for comfort. I think the ride is about 3 hours, maybe a bit less. Once at Batangas port, which the bus can drop you off at, you'll catch a Seacat ferry to PG. Suggest you have accomodations rpior to going but there are many resorts and hotels to choose from as well. It's pretty straight forward and easy. Both bus fare and ferry fare is pretty reasonable.Have fun
